The department is named after river Aveyron (250 km),
tributary of the Tarn.
On 4 November 1808, the canton of Saint-Antonin-Noble-Val was transferred from the department of Aveyron to the new department of Tarn-et-Garonne.

The former flag of the General Council of Aveyron is green with the
Council's logo in the middle. This flag is now obsolete since the General Council has a new logo.
The former logo of the General Council of Aveyron is a white rectangle with a green, smaller rectangle, charged with an orange-yellow letter "A" and
the white writing "AVEYRON", surmounting the white writing "CONSEIL
GENERAL" and a thin horizontal green stripe.
